Diverse
Redundancy Design Concept
Pinnacle safety light curtains utilize the diverse redundancy design concept.
This gives the safety light system a higher level of redundancy and control
reliability. The two microprocessors are of different design, and the
microprocessor or parallel programs are run and made up from different
instruction sets written by different programmers.
Self-Checking
Circuitry
Pinnacle safety light curtains self-check every 20 milliseconds. Self-checking
is the ability to electronically verify that all of the systems critical
internal circuit components and their redundant counterparts or back-ups
are operating properly.
Extra
Safe Design
The MicroGuard® provides two methods of fail-safe design. One utilizes
two microprocessors and two captive contact relays, and the other uses
four watchdog timers monitoring the system and the captive contact relays.
Redundant
Captive Contact Safety Relays
Redundant relays assure safety if an output relay should fail. The MicroGuard®
utilizes safety relays which have force-guided contacts. This is a configuration
where the contacts are mechanically locked together so that if one set
of contacts weld, the other contacts cannot change state. If one should
fail, the code "Relay Fault" will be displayed on the diagnostic
message display. The complete guarding system consists of two miniature
pylons with a controller for system diagnostics and wiring interface.
External Diagnostic
Message Display
Standard on all Pinnacle MicroGuard® safety lights is the "External
Diagnostic Display."
Alpha-numeric
Plain English Messages
The scrolling message display shows status and fault codes of the unit.
This is an excellent safety and maintenance feature, which is unparalleled
in the machine guarding industry for enhancing machine utilization.
Control Reliable
System
Critical components of the MicroGuard® are duplicated so that a single
component failure will not cause an unsafe condition. If a component does
fail, the units self-checking circuitry recognizes the situation and initiates
a safe stop of the machine. The fault is then displayed on the message
display.
Powerful Infrared
Light Source
Pinnacle safety lights utilize powerful, safe and predictable infrared
light as its sensing source. This gives the system greater reliability
and enhances machine utilization by minimizing nuisance trips and shutdowns
caused by dirt, coolants, lubrication mists and machine oils. Pinnacle
safety lights are highly immune to EMI, RFI, and ambient light conditions
and are unaffected by strobe lights and weld flash generated light sources.
Extensive
Testing
Pinnacle safety lights incorporate extensive testing and burn-in to establish
a high degree of product reliability and safety.
